The design
of a given artefact in the real world won't change unless specifically acted on.
A garment, or
an automobile, or
a building remains as it was originally designed, modulo wear, until and unless it is altered, modified, or renovated.
With digital artefacts, especially SAAS, where each individual use is fetched anew from a server, there's no such material stability.
Product lines are subject to revision, though even here, changes seem to follow marketing rather than functional logic. This is especially true when comparing, say, industrial vs. consumer products, particularly those with a common underlying design or base.
Examples which come to mind are Hobart vs. KitchenAid mixers (both manufactured by the same company), consumer automobiles vs. the Checker Taxicab. The last production year of Checker, 1982, could have graced a dealer's lot in the late 1940s:

Commercial jet airliners have seen at best marginal evolution since the introduction of the 707 in 1958 (and arguably for a decade prior to that). More recent design changes have finally begun to emerge largely thanks to advances in materials technology. Yes, there's been a great deal of change in avionics, flight control systems, overall infrastructure, and powerplants, but the overall design of a sausage on wings with gets slung from wings or fixed to the fuselage has remained fundamentally unchanged, largely due to laws of aerodynamics.
Railroad oil tank cars strongly resembling the present-day DOT-111 standard emerged by the late 1860s. It turns out that there are only so many viable arrangements of material for handling bulk liquids on standard-gague rails given car dimensions, curve radius, braking, bogey capacity, and the like.
The modern high-tension electric transmission line pylon dates to the early 20th century. It was the failure of what seems to have been an orginally-installed hanger hook which seems to have precipitated the 2018 Camp Fire in California, responsible for destroying the town of Paradise, CA, amongst numerous others.

Clothing, particularly in an age of disposable ("fast") fashion does change quickly, yes. But that's through continued iteration and replacement of individual items, not, generally, by the repurposing of existing garments (accessorising and similar modifications excepted).
Matter has persistence. Digital does not.
